The idea of the prince of mud incense is that we Xia people are nomadic tribes, and there is no need to stick to Tongwan City, so sooner or later we will be besieged and destroyed by the Tang army that is marching step by step, so we might as well divide it into several parts, abandon Tongwan City, chase water and grass in the Shuofang Desert, and eat meat and drink cheese when we are hungry and thirsty. If the Tang people come to attack in a big way, we will escape into the mountains, the frost and snow in the north are severe, and the soldiers and war horses of the Tang people will not be able to support it for long, so that in the natural situation, our Xia people have the advantage, and when the other side is unable to exterminate us and retreat, we will gather together again, waiting for the opportunity to take down a few fortresses, we can regain momentum, maybe the situation will change by then, and the Xia country will be expected to rejuvenate.

Yuan Hui on the seat lowered his head, pondered and distressed for a long time, and finally he laughed, pointed to the crown on his head in a gloomy mood, and then pointed to the silk robe on his body, and finally stood up and looked at the magnificent palace around him, and finally said to the prince of mud incense:

"Did I deserve all of this? No, it was all the leaders of the Xia people who swore to the sun of the great river in the east after climbing the cliff of Luzi Pass, and made a wish to the ancestral mountain and Helan mountain in the west, and supported me to become the 'son of heaven' of all Xia people. The Xia people gave me everything, but I have never been able to do anything for the Xia people, now the foundation of the entire Xia state, in this Tongwan City, I must not flee from the wind, I am willing to lead 10,000 Xia people in the Tongwan City to hold on, you lead others, do what you want, we work together inside and outside to insist, maybe there is more turnaround. ”

"Your Majesty!" The prince of mud incense was also ready to make further persuasion, but he was pressed by Yuan Hui's shoulder, and the Qingtian Son had made up his mind, "The enemy towers of Tongwan City all have nine fortresses, and the city walls are extremely fine, and arrows are invulnerable, even the kind of fire of the Tang people can't break it." You took the rest of the cavalry and galloped in and out between the Wuding River and the north and south of the Heishui, waiting for the opportunity to plunder the Tang army's grain route. ”

After finishing speaking, Yuan Hui took his two sons Yuan Long and Yuan Sheng out of the curtain behind him and entrusted them to Prince Nixiang: "The two princes will act with you, if the war is unfavorable, and the city of Tongwan has a long and short time, you can continue to persist in the name of Qingtianzi, recruit troops and horses, and rejuvenate Great Xia." ”

"Your Majesty......" Prince Muxiang choked up and bowed to Yuan Hui.

At this time, Gao Yue's camp was stationed in Yinzhou Yuhe Fort, which was ninety miles northwest of Mizhi, and then traveled one hundred and twenty miles west along the Wuding River from Yuhe Fort, and you could reach Tongwan City!

Yuhebao is the meeting of the Diyuan River (Mingtang River) and the Wuding River, and it is Linzhou to the north along the former, and Xiazhou is to the west along the latter. At this time, the autumn wind hunting, the flag is flying, Gao Yue wears the cloud floating sword, accompanied by the generals, rides across the pontoon bridge on the Diyuan River, and then ascends the Yincheng Pass opposite the Yuhe Fort.

This pass gradually rises to the northwest, and finally rises into a superb mountain, except for the southwest corner, the rest of the sides are mirror-like cliffs, sandwiching the north bank of the Wuding River, becoming the key to the east and west.

Gao Yue rode his horse and whipped his horse, and went straight to Yincheng Pass.

The plains of the river to the east of the pass are full of camps of the Tang army and the familiar Qiang Yicong.

Looking to the west, Gao Yue knew that the ultimate goal of his expedition was there.

He held the horsewhip, and Cai Fengyuan held a bronze map of Tongwan City in all directions and stood in front of the horse, showing it in front of Ji Gong and other marshals and generals.

"Baichengzi has been mentioned many times by historians in the classics, saying that the Wuding River and many mountains are in the south, and the river surrounds the city from the southwest to the northeast, and the city is lofty, which is definitely not something that can be captured by manpower." At this moment, Gao Yue sighed.

Han Tan, Guo Zaizhen, Gao Gu, Ming Huaiyi and other generals who were present all changed their faces when they heard Ji Gong personally say that Tongwan City "is definitely not something that can be captured by manpower", "Is it possible that this time you want to lose troops and lose troops and waste money and food in this Tongwan City?" ”

But in an instant, Gao Yue suddenly laughed again, and said to everyone: "What I said before is just what the historian wrote on the scroll, and it is possible to exaggerate it, if the city of Tongwan is really indestructible, why did Helian Bobo die in the second generation?" In my opinion, the fatal weakness of Tongwan City is not in its west, east and south, but only in its north, yes - it is the black water of Emperor Taiwu of Later Wei to destroy Helianchang! ”

In fact, Tongwan City was breached two years after Helian Bobo's death.

And was broken very bad, when the Northern Wei Emperor Taiwu made up his mind to destroy the summer, he only led 18,000 light cavalry in the second year of Chengguang (426), set off from Pingcheng in the winter of that year, crossed the Yellow River, covered Helianchang, at that time the cavalry of the Northern Wei Dynasty was to the north of Tongwan City more than 30 miles of Heishui under the camp to line up, Helianchang was unprepared, hastily went to battle, and was defeated, the cavalry of the Northern Wei Dynasty has been rushing into the west city, plundering the Xia people and returning.

In the second year, Emperor Taiwu led 30,000 cavalry to cross the Yellow River, and also set up camp in Heishui, not waiting for the follow-up infantry and siege equipment to keep up, and fought with Helianchang in the north of the city.

Therefore, Gao Yue believes that the best way to attack Tongwan City has already been told to him by Emperor Taiwu of the Northern Wei Dynasty four hundred years ago - it is obvious that the south and east of Tongwan City, because the Wuding River surrounds the city wall, forming a double trench, where it is difficult to deploy the army to attack the city, but the north of the city is different, and it is more than 30 miles between Heishui and Qiwu Mountain, which is a flat place conducive to cavalry galloping battles.

What the? Dang Xiang is good at cavalry combat?

But now, my Tang cavalry, will they be afraid of this group of barbarians who are scarce even in armor and iron arrows?

At this moment, Gao Yue had made up his mind, he raised his horsewhip, and first pointed to Diyuanchuan, "Dingwu and Yining armies have a total of six battalions of 4,800 cavalry, plus 6,000 Shuqiang Yi cavalry, march north along this Sichuan, detour to Woyebo further north of Qiwu Mountain, and wait for Xu Baohui of the Tiande Army, Kang Rizhi of the Shuofang Army, and the cavalry of Dumenlang on the West Road to join the division, and then go south to attack Heishui in the north of Wancheng!" ”

Immediately, he pointed the horsewhip to the west of Yincheng Pass, "Gao Gu and Zhang Jing led the two armies with a total of ten general foot soldiers, righteous servants, chariot guns, and large bronze cannons, etc., to attack east of Tongwancheng along the Wuding River, using this as the main soldier to confuse Tuoba Zhaohui." ”

"At the same time, quickly send people to inform the soldiers and horses of Jia Fujiao and Gao Da on the West Road, and continue to arrive at the Hongliuchuan River in the south of Tongwan City."

The generals immediately accepted the order, and Ming Huaiyi also took the initiative to ask Ying to say, the cavalry in the direction of Diyuanchuan will be handed over to me to command, and the infantry artillery in the direction of the Wuding River will be handed over to Gao Gu and Zhang Jingze.

However, Gao Yue's words below shocked everyone: "This cavalry has penetrated deep into the enemy's dangerous place, and the soldiers must work together, how can I, as the commander, sit in the tent?" The cavalry attack in the direction of the Teiyuan River was personally led by me. ”
